For Websites - Développeurs Facebook. As mentioned, the code above uses the common defaults for the options available when initializing the SDK. You can customize some of these options, if useful. Changing SDK Language In the basic setup snippet, the en_US version of the SDK is initialized, which means that all the dialogs and UI will be in US English. You can change this language by changing the js.src value in the snippet. Take a look at Localization to see the different locales that can be used. <script> (function(d){ var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/es_LA/all.js"; d.getElementsByTagName('head')[0].appendChild(js); }(document)); </script> Disabling Login Status Check By setting status to true in the FB.init() call, the SDK will attempt to get info about the current user.
Setting status to false can improve page load times, but you'll need to manually check for login status using FB.getLoginStatus. Extended Permissions - Développeurs Facebook. Permissions are a form of granular, app user-granted Graph API authorization. Before your app can use an API endpoint to access your app user's data, your app user must grant your app all permissions required by that endpoint. Only select permissions that your app needs to function as intended. Selecting unneeded permissions is a common reason for rejection during app review. You may also use any permission granted to your app to request analytics insights to improve your app and for marketing or advertising purposes, through the use of aggregated and de-identified or anonymized information (provided such data cannot be re-identified).
Requirements Ways to ask for a permission When your app users log onto your app, they receive a request to grant the permissions your app has requested. If your app does not use a permission for 90 days, usually due to user inactivity, your app user must regrant your app that permission. Remove a permission. Authentification - Développeurs Facebook. Implementing Facebook OAuth 2.0 Authentication in Java | Pragmatic Coder : Java, Wicket and the Web.
Published Wed, 30 Jun 2010 • 100 comments I recently switched onmydoorstep.com.au's Facebook login feature from the old "Facebook Connect" API implemented with facebook-java-api over to the new Facebook Graph API / OAuth 2.0 authentication. This was far easier to implement than the original authentication, particular under Apache Wicket, but it should be easier regardless of your Java framework of choice. Here's how I did it. First I developed a basic "magic" class for the Facebook API - You'll need the visural-common library for some of the code above. I want the "email" and "publish_stream" extended permissions, so that I can get the user's email address and post updates back to their stream in Facebook. The process of authentication is simple.
Due to the way Apache Wicket works, I implemented a Servlet Filter for the "redirect_uri" (/fbauth) - Your "UserService" might look something like - So, just to recap, the sequence of authentication is as follows - Anyhow, hope it helps someone out! Graph API Overview - Développeurs Facebook.
